Don't matter where or when it is, if I see an RVer on the side of the road, I always stop and offer help. Most of the time my help is not needed, especially when the stop is needed because the kiddo's needed to use the bathroom! I'll pass on that one, thank-you!
But I have helped. Like the poster above, I once flagged a TT driver down because the rubber on his roof was literally ripping completely off and flopping behind the camper.
Another time, an older couple (on I-460 around Indianapolis) had their awning start flopping. It caught my attention and I passed them and flagged them down. They finally pulled over. I help the guy get the awning down as I had a ladder in the back of my pick-up.
Another time, traveling with the camper, we were on a back road with no exchange to the interstate below. When crossing over the interstate, I noticed a 5er pulled forward from under the overpass and a lady and a couple kids just sitting in the grass. I pulled the camper over, got out, climbed over the embankment and asked if they needed help. They said "no" the husband had just left with someone else who stopped (on the interstate), and was heading to a service station. They had a flat tire on the tow vehicle.
There are more stories I could share, but these 3 were the most memorable, probably because they all involved a little bit of drama. I asked each person (and I've helped many) to do only one thing in return for my efforts to help them. And that one thing is, if they ever see an RVer on the side of the road, to stop and help them too, because that person on the side of the road may someday be me!
